Comment: review:
I could post and prove 100 inaccuracies, but I will cover just one point, let me review chapter
VII, p189-197; INTAKE mods.
He is only trying to get you to buy expensive induction mods.
He never mentions the down sides. oop's ( that is the smoking gun )
First of all, he fails to mention that these changes only improve the breathing of
the engine at wide open throttle. A place that most people never reach.
He make blanket statements about gaining 8HP , but he never said on what size engine,
a 50HP smart car with 1000cc or 7 liter monster truck engine. Funny huh?
Blank statements are almost always wrong.
Consider this:
messing with the inducting will most likely foul up the function of the MAF sensor.
Removing the screen (a laminar air controlling device really) or any changes can
cause the MAF to read incorrectly and to read wrong at different RPM.s
This is really foolish.
or
Bad #2:
Oil soaked washable open air filters will coke up the MAF sensor with oil.
Greater HP is an outright fallacy.
The MAF sends the AIR flow values to the ECU the Oxygen sensor brings the engine to NEAR
the best combustion point 14.7 (A/F ration by weight) 15.6 is best MPG on most cars.
So, no matter what you do (save damaging the MAF readings) the car will always give the same MPG if these two sensors are working to spec.
Many false statements and many fibs by omission.
feeding air straight in to the throttle body will defeat the purpose of the MAF.
ALL MODERN ENGINES USE A MAF SENSOR. ( There are exceptions ,like a Jeep 4 Liter i6)
The #1 biggest restricting device to power, is the Throttle valve ,it is restricting at 70%
while drive down the highway at 60 MPH. ( in fact, that is its job, it controls power)
The #2 is the Size of the Intake valves.
A larger Throttle body will not increase power with out major engine changes.
Nor will silly throttle plate adapters .
Before you change anything, My I recommend that you review other peoples work using a dyno where they have worked hard and proven all the myths , true or false, on your exact car.
You can tune for power or MPG but not both. Read the Forums of MegaSquirt (tm).
(but a custom ECU can do both "the dual map trick") ( not on your ECU)
An Otto cycle automobile engine is an air pump; in order to pump more air , one only needs to study where the REAL restrictions are located and there magnitude.
Once that is learned , you can begin experimentation.
The book is very good in its coverage of what can be done but is weak on facts.
I check to Manufactures TSB data bases and found both to contain the order of not
honoring the warrantee with MODS to the engine. He calls this "Scrutiny", with a light mention. Not to mention the Smog station.
I have studied many TRACK tests that show no so called COld air induction kit improvements, with the exception of building a funnel box in the front of the car to scoop up air , or by taking the naturally pressurized air from the vent cowl below the windshield (if you have one).
this test must be done on a track because the car is not moving on a Dyno.
I hope I open some eyes on how to get to truth. ( testing , with control groups).

Customer Rating: Summary: How to customize your street machine.
Comment: I wasnt sure what to expect with this book purely because of the inappropriate title,which doesnt do this book any justice.However,the book is better than I had hoped.Here's why:
This book is about customizing your car.Its a comprehensive-detailed book explaining how to customize your car. It covers so many things,which make this book a rarity.It tells you what to consider as well as what to avoid.
There are 2 faults with this book:
1)the innapropriate title.It should have been titled something more specific.
2)These series of books dont have photographs,just drawings.And,thats the bad news.
The good news is this book offers great advice on customizing your car.Its great value and a great book.Highly recommended.
Ignore the title.Its a book on customizing your car.
